Illustrator and Photoshop - Drag items from a canvas to another isn't working on Windows 7

I updated to the new photoshop (2015.1.1) and since this new version (2015.1) there is a bug where I can't drag items from illustrator canvas and drop into the Photoshop canvas any more. If i try to drop something from illustrator into photoshop, nothing happens, and no error message is displayed.
